TSB–88 For Public Safety LTE
Proposal: release documents in phases ◦ First release: Basic LTE coverage modeling and verification concepts such as tile reliability, service area reliability, data rate channel performance criterion, etc. High-level overview of additional key LTE concepts Significant benefit in defining these basic coverage modeling and verification concepts e.g. industry conversations have revolved around questions like “what is LTE coverage”, “what do you measure to validate LTE coverage”, etc. Focusing on key concepts will accelerate document development and delivery 2
Front matter ◦ Forward, introduction, scope statement, and references Definitions and abbreviations ◦ Key LTE coverage modeling definitions such as Data Rate Channel Performance Criterion (DRCPC), Tile Reliability, Covered Area Reliability, Service Area Reliability, etc. 3
LTE Technical Performance Definitions and Criteria ◦ Scope for First Document Release Service Area Data Rate Channel Performance Criterion (DRCPC) Contour Reliability Tile Reliability Tile-Based Area Reliability Subscriber Distribution Traffic Models and Loading Need to relate model load to field validation load Resource Block Sharing 4
Front Matter ◦ Forward, introduction, scope statement, and references Definitions and abbreviations ◦ Key LTE coverage verification definitions such as Data Rate Channel Performance Criterion (DRCPC), Number of Test Tiles, Tile-based Area Reliability, Validated Service Area Reliability, etc. 5
